Abstract
The disclosure relates to a multilayer panel for producing a floor covering, comprising a wear layer bonded to a back layer, said back layer being made up of at least a thermoplastic material, a plasticizer and fillers, the wear layer comprising a surface layer made up at least of PVC, said surface layer having a Shore D hardness greater than or equal to 60 and a Young's modulus greater than or equal to 1000 MPa.
Claims18
A multilayer panel for making a floor covering comprising a wear layer bonded to a back layer,
- wherein the back layer is derived from at least a thermoplastic material, a plasticizer and fillers,
- wherein the wear layer comprises a surface layer derived from at least polyvinyl chloride (PVC), the surface layer having a Shore D hardness greater than or equal to 60 and a Young's modulus greater than or equal to 1000 MPa,
- wherein the surface layer comprises impact absorbers;
- wherein the impact absorbers are polymeric plasticizers;
- the index of refraction of the incorporated impact absorbers being comprised between 1.52 and 1.55 at 20° C., and
- wherein the polymeric plasticizers are thermoplastic polyurethane (TPU) particles.
